Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2H-Oxazolo[4,5-f]indole.
2H-Oxazolo[4,5-f]indole (CAS 70814-40-3) is a high-purity analytical reference standard with the molecular formula C9H6N2O and a molecular weight of 158.16 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2H-Oxazolo[4,5-f]indole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2H-Oxazolo[4,5-f]indole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
